kernel: ar8327/ar8337: disable ARL access code to avoid lockups (FS#384)
Running ar8327_get_arl_entry() early after boot leads to MDIO related system
lockups on several devices using this driver.
Since dumping the ARL table contens is an optional, uncritical feature, simply
disable the code for now.
